IMPROVEMENT IN COMPOUND' MACHINES PoR SHEARING, PUNCHING, UPSETTING,

AND BENDING METAL.

The Schedule referred to in these Lettes Patent' and making part of the sa'me.

To all whom tt may concern:

Beit known that-I, WRIGHT Steenen, of Coaticooke, in the province of Quebec' and Dominion of Canada-have invented certain -new and useful Improvements 1n Shop-Machines for Shearing, ']?unch ing, Upsetting, and Bending Metal and I do hereby. v

declare thefollowing to be a full, ciear,-and .exact description of vthe construction and. operation of the same, reference being had to the accompanying drawings making apart of this specification-,in which- Figure 1 represents a perspective view of the ma-l chine, looking-toward one of its sides;

`Figure 2 represents a perspective vicwot vthe machine, taken from its opposite side; and Figure 3 represents a vertical longitudinal section through the machine.

Similar letters'of reference,'where they occur in the separate figures, Vdenote like' partsofthe .machine in all of the drawings.

llhisy invention relates, mainly, to the' manner of operating the lnan level', and, .through the main lever, the several devices connected wit-h it, lfor shearing, punching, upsetting,'. andbending metals,'so as to admitof its being readily and conveniently operated asa shop-machine, -and by one person, if nec'essary. i

lo enable others skilled in the art to make and ,use my in'vention, I` will proceed to describe the same, with reference to the drawings.

rlhe. bed or fra-me A of the machine maybe'cast Atv the point a in the frame is hung the vlmain lever B, the rear end of which is bent downward, and furnished withanjinternalrack, b, into which a' pinion, C, operated by a lever,`D, takes, -f'or operating said lever. On the main frame A' there is cast an arm, A', the upper end of which-is' roundedout, as at c,'to form an. anvil-die,fi11to whicha similarly-roumled projection, d, on` the lever-B, tits andvpresses,this being. for the purpose of bendingmetal into a curved" form.

0n the' portion A" of the frame is' fixed a shearbi'ade, e, andi-on the lever B' is iixed a sl1ear blade,f, which two blades forma shears for shearing metal. On top of the main frame'gis cast, or. otherwise formed, a recess, g, and'in it is hung acl'amping lever, i, and near this recess, so as to form a continuationof it, is a-slidin'gfpiece, E, which has also a clamping-lever, i', hung in or on it, which A"sliding piece has in its under portion' rackftee'th,j, into 'which similar teeth, on the main lever,-take, so as to moic the clamping-piece E.

This :mechanism isforupset-ting iron, shortening tire, 8m.

To the fron-t endet` thel lever. 15, whereit projects throughor beyond the main frame, ishung, by a st-irrup', l, a' die-stock, fm, which carries a die, Ta, said die-stock being guided in "its motions, by passing through a 'projecting piece, F, cast on the frame.

rlhe counter-dieo is, set and adj-usted'iu abred,^Gr',`

which is also a part'of the frame, and may be'move'd longitudinally to' change the counter to conform vto the punchiug-die, o1" turn amanda-center, that will always bring them under the punch.

Attached to the main frame, there may bear-oli; frame, H, in which a seriesof rolls, p p p, may be set, adjusted, and operated by means 'ot' a crank on the shank q, these rolls being for the purpose of rolling tire.

The advantage of -the internal gear 'lr .0n the -lever is that, the operator may work the lever'D, and, 'a the same Vtiine, si:4andby and hold the iron under thel shears orpunch, and said shears andpunch be both under his close observation, which couldvnot be the case'if' the rackb were on the' outside ofgthe curved tailpiece ofthe lever. l v

The leverDiits into a socket, s, which may becast on and with the pinion C, and the lever-isbent, as shown by thedottedlines, morevparticularly in tig. 3, so that byV turning it in its socket ,it'will adapt itself better tothe 'location lof .the operator, who'ca'n both handle -t-he iron v-he is workingV upon, and .at the Sametime operate rthe'- lever to work the shears or' the punch.

-'The upsetting mechanism will be readily under-v stood.

The piece E, being moved 'out a suitable distance, the bar to -be upset is lrigidly clamped in the bed or recess, and against the vert-ical pieces t. The vslide E 'is now run bacl\',1and the metal correspondingly upset.v

or jammed up.A

-A small button or roller, fr, ot" Ist-eel, i s placed between the lever B and t-he die-stock m.to allow said die-Stoch to move'truly through vits guide F.

Having thusfully described vmy invention',

l. The arrangement of the internal gear b, onv the main lever B,'and the pinion O, and hand-lever D, working therewith, so`that the hand-lever-shall ex tend forward'and be used at the vfront of the machine by the operator standing there, as described.

-2.'In combination with the lever B,`and ywith theslide E of the upsetting mechanism, the cogs or teeth j and "It, for moving said slide, as set forth.
